Quadruple differential line driver | DW | 20 | 0 to 70

The SN75ALS174 is a quadruple line driver with

tri-state differential outputs. It is designed to meet the requirements of ANSI

Standards EIA/TIA-422-B and RS-485. This device is optimized for balanced multipoint

bus transmission at rates of up to 20Mbit/s.

Each driver features wide positive and negative common-mode output voltage ranges that make them suitable for party-line applications in noisy environments.

The SN75ALS174 provides positive- and negative-current limiting and thermal shutdown for protection from line fault conditions on the transmission bus line. Shutdown occurs at a junction temperature of approximately 150°C.

The SN75ALS174 is characterized for operation from 0°C to 70°C.
